ROUN DAB OUT Specification of Letters Patent.

Patented May 25, 1909.

Application filed March 9, 1907. Serial No. 361,524.

To all whom it may concern:

Be it known that I, CLARENCE D. SAUvn, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Roundabouts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to round-abouts and has for an object to provide a round-about embodying new and improved features adapted to tilt the rotating platform.

A further object of the invention is to provide in a round-about new and improved means for varying the angle of inclination of the rotating platform.

A further object of the invention is to provide in a roundabout a rotating platform with means for tilting the platform and improved means whereby the platform may be continuously rotated at a given inclination to a vertical with or without carrying the inclined platform around the central axis of the body, thereby either giving to the platform a simple rotation upon its own axis, or adding to such rotation a revolution, as it were, in an inclined position round the frame of the structure.

With these and other objects in view, the invention comprises certain novel constructions, combinations and arrangements of parts, as will be hereinafter fully described. and claimed.

In the drawings :Figure 1 is a vertical, sectional View of the improved round-about. Fig. 2 is avertical, detail, sectional view similar to the view shown in Fig. 1 of the tilting mechanism on an enlarged scale. Fig. 3 is a horizontal, sectional view of the tilting device taken on line 3-3 of Fig. 2.

Like characters of reference designate corresponding parts throughout the several views.

The improved round-about forming the subject-matter of this application comprises a structure of any approved design shown here as the posts 10 braced in any approved manner as by the braces 11 and with a platform or plate-like portion 12 secured upon and joining their upper ends.

Centrally upon the platform or plate-like I portion 12 is erected a tapered, hollow column 13 having at its upper end a substantially spherical head 14 with an opening 15 at the top of the said head and an opening 16 at the lower side of said head communieating with the tapered hollow interior of the column 13.

Upon the head 14 is mounted a hood 17 provided with a concavity in its lower side proportioned to bear and fit upon the spherical exterior of the head 14. Extending upwardly through the hood 17 in a normally vertical position is a shaft 18 preferably rigidly connected with the hood and extending upwardly above the head and provided with a head 19 and downwardly through the interior opening of the column 13 and below the plate 12 and provided. with a universal joint 20. A shaft section 21 extends downwardly from and is connected with the shaft 18 at the universal joint 20 and provided with another universal joint 22 which, in turn, is connected with a shaft 23 j ournaled in any approved manner as in the bearings 24, and having at its lower end means for rotating the shaft here conventionally shown as the belt pulley 25, although it is to be understood that any approved means for imparting rotary movement to the shaft 23 and its associated shaft sections 21 and 18 may be substituted for the belt pulley 25. Encircling the structure represented by. the posts 10 is a platform shown conventionally at 26 which may be of any approved size and form and carry thereon any approved or desired means for the accommodation of passengers. The platform, at 26, is suspended from the hood 17 by means of guys 27 and is further supported by other guys 28 from the head 19, whereby a rotary movement of the shaft 18 is imparted to the hood 17 and head 19 and through the guys 27 and 28 to the platform26.

Beneath the plate 12 is journaled a gear wheel 29 in any approved manner as by the employment of a flange 30 upon the said gear wheel interengaging with an annular flange 31 formed upon the under side of the plate 12. The gear wheel 29 is provided with a slot 32 positioned to permit the shaft 18 to be disposed concentrically with the said gear and extending radially from the said central position to permit the movement of the shaft 18 in the said slot to the position 18 and to v inclination to a horizontal.

34 through which the shaft 18 extends and in which it is journaled. To compensate-for the change in the angular position of the shaft 18 incident to its movement to the position 18 or intermediate positions the block 34 is mounted upon apin 3-5 by means of which connection with the guides 33 is provided which permits the angular movement of the block 34 relative to the guides and to the gear 2 9.

The position of the block 34 radially to the gear 29 is controlled by means of a screw 36 pivoted by means of the head 37 uponthe pin 35 and actuated by means of a nut 38 embracing the said screw 36 and journaled in bearings39. The nut 38 is rovided with gear cogs 40 forming a bevelec pinion thereon, which said pinion is intergeared with a pinion 41 carried upon'tlre upper end of a shaft 42 and controlled by any approved means as the hand wheel 43 The gear 29 is rotated in any approved manner as-by the pinion '44 on a shaft 45 j'ournaled in bearings 46 and intergeared-by means of gears 47 and 48 with the positively driven shaft 23. The shaft 45 is preferably connected with the gear 47 by means of:a clutch conventionally shown at 49 by means of whichthe said shaft 45'may be disassociated'from the gear 47 permitting the shaft 45 to remain stationary while the shaft 23 is being rotated.

With the'parts disposed as shown in full lines in the drawings, the platform 26 will be disposed substantially horizontally and will rotate with the rotation ofthe pulley 2 5 in a substantially horizontal plane. When it is desired to tilt the platform 26 the hand wheel 43 is rotarily moved rotating thereby the nut 38 andmoving the block 34 and the shaft 18 to the position 18 or to a position intermediate the full line anddotted line positions shown.

With the clutch '49 disassociated it will be apparent that the shaft 18 will rotate at an inclination to a vertical, but rotate continu-'- ously at such-inclination and'that the lat form 26 carried thereby will rotate at aiixed VVhenit is desired to cause the latform in its inclinedposition to rotate about the whole structure, which movement taken in connection with its rotation with the shaft, might be called a sun and planet mot-ion,it is only necessary to connect shaft 45 with the gear 47 by means of the clutch '49, and as-the shaft 23 rotates with the'belt pulley 25-to rotate the platform, the shaft 45-is also rotated, rotating thereby the gear 29 at a ratevery much lower than that of shaft 23 due tothe fact that the gear 29 is muclr larger than the pinion 44, and the gears 47 and 48-are-nearly equal in diameter. The shaft being in an in- 'clined position, such as the position 18 shown in dotted lines in Fig.1, and engaging in slot in the gear 29, will thereby be carried around the vertical axis with the gear 21 when rotated as described.
